Abstract [en]

The rate and activation parameters for oxygen exchange of the mu(3)-oxo bridges in a manganese tetranuclear cluster with (H2O)-O-18 have been measured by ESI-MS; the observed Delta S double dagger of -146 +/- 22 J K-1 mol(-1) is consistent with the expected associative mechanism of substitution.
